The Windows debuggers can run on x86-based, x64-based, or ARM-based processors, and they can debug code that's running on x86-based, x64-based, or ARM-based processors. Sometimes the debugger and the code being debugged run on the same computer, but other times the debugger and the code being debugged run on separate computers. In either case, the computer that's running the debugger is called the host computer, and the computer that is being debugged is called the target computer. The Windows debuggers support the following versions of Windows for both the host and target computers.
